66Abstract:
Complex regional pain syndrome (CRPS) is a significant complication in operated osteoarticular pathology and may adversely affect patient's quality of life. Vitamin C is an anti-oxidant and a neuro-modulating agent. Intake of vitamin C appears to be the only preventative factor. The objective of this study seeks to assess the effectiveness of liposomal conditioning of vitamin-C in reducing CRPS and to show evidence that it is more effective than taking vitamin C in its usual form.
Methods:
Three series of patients undergone for identical pathologies the same surgery performed in the same centre by a single surgeon using the same operative techniques and the same implants. The first group took vitamin C in liposomal form. The second one took classical vitamin C tablets while the third one received placebo pills. Comparison was made between both groups which were identical in number and were the same average age. Results were compared and analysed at the end of one-year follow-up.
The intake of liposomal vitamin C at 500 mg, in the morning and evening, one week before surgery, one during the day of surgery and lastly, during the first 21 post operation days.
The intake of traditional vitamin C with a daily intake of 500 mg in the morning and evening for 28 days (starting 7 days before the operative procedure, on the day of the surgery and ending twenty-one days after surgery).
The intake placebo was taken daily in the morning and the evening for 28 days (7 days before surgery, on the day of surgery and twenty-one days after the surgical procedure).
Received allocated conventional vitamin C (n= 22) Did not receive allocated conventional vitamin C (n= 0)
Received allocated liposomal vitamin C (n= 22) Did not receive allocated liposomal vitamin C (n= 0)
Received allocated intervention (n= 22) Did not receive allocated intervention (n= 0)

We take an x-ray of the knee then we calculate of the Index of Caton and Deschamps AT / AP which must be close to 1 cm (from the upper edge to the lower edge of the patella which must be equal to the distance between the tip of the patella and anterior tibial tuberosity) to be interpreted as a transposed tuberosity.
Radiographs of the knee in monopodial support at 30° flexion (schuss) were taken. Measurement analysis of the translation of the tibia relative to the femur which must be close to 0 cm for the patient to be positive for the outcome.
Radiographs of the knee in Schuss with an external decoaptation which must be close to 0 cm and a pan gono gram standing from the front
X-rays of the knee and Schuss profile with an internal and external decoaptation which must be close to 0 cm with pan gonogram standing from the front (x-rays of the long axes of the pelvis of the ankles with measurement of the HKA axes on the prosthesis side and on the non-side operated which must be close to 180°) to have eccentric arthritis.
